一、简介
AdMob 是移动电话广告市场，可提供用户在移动电话网络上播放广告。2006年AdMob创建于加州。移动网站（Mobile site）可选择加入AdMob，并启用AdMob的广告轮播，广告则在AdMob网站中置放。目前iPhone与Android手机上皆有此功能。2009年11月9日Google宣布以7亿5千万股份购入AdMob，正式投入移动设备上的广告市场。
Admob覆盖200多个国家，是美国最大的手机广告平台。

二、广告类型
总共分四种。
分别为：Banner（横幅广告） 、Interstitial（插页广告）、Rewarded Video（激励广告）。
Banner（横幅广告）：最常见的，就是平时看到的屏幕的底部或者顶部有一个横条的广告条。
Interstitial（插页广告）：类似启动页广告，整个屏幕显示一副广告。
Rewarded Video（激励广告）：这个玩国外游戏经常会看到，你看完一个广告视频，游戏会奖励你一些道具或者其他的什么（这个奖励是一个整数，在AdMob中可以设置数量，用户看完视频会得到这个数量的奖励，比如奖励3瓶药水，3条生命等。）。
广告单元
三、 实施过程
unity引擎在接入Admob广告时，过程非常简单：
1、首先下载googleads-mobile-unity， 链接为：https://github.com/googleads/googleads-mobile-unity
注意：点击上图红色部分releases跳转的位置可以选择自己需要的SDK版本。下载完插件，把插件里包含的GoogleMobileAds.unitypackage的文件导入你的项目。 导入项目后你的project里面会出现以下文件。
2、申请广告id
（1）前往AdMob官网注册账号，使用自己的Google账号即可（已注册的童鞋跳过此步骤）；
链接：https://www.google.com/admob/
（2）注册完成后，登陆账号，即可进入AdMob管理中心，如下所示：
在此界面，可点击左侧边栏中的选项进行信息设置，在此不在赘述。
（3）账号申请完成后，即可为自己的应用申请相应的广告id了，选择左侧边栏中的 “应用” 选项，如下图所示：
选择后，在右侧将会出现弹出窗体，点击窗体左下角的 “ 添加应用 ” 按钮：
在弹出界面填写应用发布信息（已发布的应用，可在此直接关联Admob，未发布的应用可在之后进行关联）：
在此篇文章中，制作一个测试案例，本人选择未发布，选择完成后，跳转至如下界面，填写应用信息，并为应用选择相应的发布平台，在此以Android平台为例，选择Android，如下图所示：
信息填写完成后，选择添加，即可成功创建自己的应用了，如下图所示：
在此图中可获取自己的应用ID，在之后的广告接入中需要配置，可提前记录下来。接下来可谓自己的应用创建广告单元，选择左下角的创建广告单元按钮，即可进入如下界面：
在此界面选择相应的广告模式即可进行创建，以横幅为例（其他两种创建方式相同），点击选择按钮，将进入如下界面，在该界面中填写广告单元名称：
点击高级设置，可进行广告单元类型、刷新频率、有效每千次展示费用低价设置：
设置完成后，点击左下角的创建广告单元按钮，即可完成广告创建。
创建完成后，将会获得横幅广告单元id，在此界面底部，可选择 “完成”：终止广告单元创建，亦或选择“再创建一个广告单元”：继续进行广告单元创建。
本次Test案例，创建两个广告单元：横幅与插页。
3、代码逻辑，针对于Admob官方SDK，本人编写如下逻辑代码，进行广告接入：
AdmobLaunch.cs: 用于配置APPID，进行广告单元初始化
using System.Collections;
using System.Collections.Generic;
using UnityEngine;using GoogleMobileAds.Api;
public class AdmobLaunch : MonoBehaviour {
void Awake()
{ #if UNITY_ANDROID
string appId = "填写自己的AppId"; #elif UNITY_IPHONE
string appId = "";
#else
string appId = "unexpected_platform";
#endif
MobileAds.Initialize(appId); DontDestroyOnLoad (this.gameObject);
} // Use this for initialization
void Start () { }
// Update is called once per frame
void Update () {
}
#region GUI Button
/*
void OnGUI()
{
if (GUI.Button(new Rect(0, 200, 200, 200), "Request _ Interstitial "))
{
GoogleMobileAdsDemoScript_Insert.Instance.RequestInterstitial();
}
if (GUI.Button(new Rect(300, 200, 200, 200), "Show Ad Interstitial"))
{
GoogleMobileAdsDemoScript_Insert.Instance.Show();
}
GUI.Box(new Rect(600, 200, 600, 200), "is ready Interstitial : " + GoogleMobileAdsDemoScript_Insert.Instance.IsReady());
if (GUI.Button(new Rect(0, 600, 200, 200), "Request _ Banner "))
{
GoogleMobileAdsDemoScript_Banner.Instance.RequestBanner();
}
if (GUI.Button(new Rect(300, 600, 200, 200), "Show Ad Banner"))
{
GoogleMobileAdsDemoScript_Banner.Instance.Show();
}
if (GUI.Button(new Rect(600, 600, 200, 200), "destory Ad Banner"))
{
GoogleMobileAdsDemoScript_Banner.Instance.Destory();
}
if (GUI.Button(new Rect(0, 1000, 200, 200), "Request _ RewardedVideo "))
{
GoogleMobileAdsDemoScript_Video.Instance.RequestRewardedVideo();
}
if (GUI.Button(new Rect(300, 1000, 200, 200), "Show Ad RewardedVideo"))
{
GoogleMobileAdsDemoScript_Video.Instance.Show();
}
GUI.Box(new Rect(600, 1000, 600, 200), "is ready RewardedVideo : " + GoogleMobileAdsDemoScript_Video.Instance.IsReady());
}

public void HandleOnAdLeftApplication(object sender, EventArgs args)

GoogleMobileAdsDemoScript_Video.cs: 激励广告接入逻辑，可配置广告单元不同状态的回调事件。

}
至此，Admob广告单元接入工作完成，创建一个空物体，将三个脚本进行挂载，运行程序，即可获得相应广告单元初始化输出信息。
4、发布应用，进行真机测试
在Unity编辑器下，我们无法进行广告单元测试，在此，可以将应用进行发布，安装到相应平台的移动设备或者模拟器进行测试（建议使用真机测试）。本次程序运行效果如下所示：
至此，所有流程已结束。
